i had this one, the aeroform costs round 250 pounds in England.
I think if you search you must be able to find the dealer; the post is around 1 year old i think..
It got me bad mileage , a very brutal noise unlike any other inductionkit, lost power i think at high rpm.. sold it to a young guy ; they love the sound
Maybe when the car is mapped to suite the filter it'll be okay (?)
ps; Real carbon heatshield, but in traffic you'll be sucking up heat anyway as the (trumpet)-entrance is above radiator
